That's because the main story is one of politics. Take out politics and the story is nothing special. These guys are astronauts, their mission just took longer than expected because people considered it was safer that way. A movie about it would as boring as a movie about people working in space can be. But political figures and the media took the story as an opportunity to do what they do best in creating "engagement", i.e. flame wars.
